Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed. July 24, 1911. Serial No. 640,276.

To all whom it may concern:

Be it known that I, JAMES J. B GKLEY, a citizen of the United States. resident of Washington, District of Columbia, havemade a certain new and useful Invention in 'Ant-ifriction-Bearings; and I declare the following to be a full, clear, and exact description of the same, such aswill enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of this specification.

Figure 1 is a plan view of the invention, showing. the load bearing rollers in place in .one half of theannulus. Fig. 2 is a section on the line 22, Fig. 1 of the invention as applied. Fig. 3 is a section on the line 3-3, Fig. 2, with parts broken away and the load bearing rollers in dotted lines. Fig. 4 is a detail sectional view taken centrally of one of the load bearing rollers.

The invention has relation to anti-friction bearings for use with cranes, derricks,

car trucks and other devices, where a weight is supported upon frusto-conical or cylindrical rollers, having for its object to enable the rollers to be readily removed and replaced in position.

Other objects and advantages will hereinafter appear.

Theinvention consists in the novel construction and combinations of parts, as hereinafter set forth. In the accompanying drawings, illustrating the invention,.the numeral 1 designates the load support or base, having an annular beveled track or raceway 2 for the rollers 3, 3, upon which is borne the load or an intermediate support for the load. marked 4.

5 is an annulus having rollers 6, 6 supporting the same, located preferably outside of the rollers 3, 3 and rolling upon a track or raceway 7 of the support, said annulus being composed preferably of inner and outer rings 8 and 9, separated by an interval 10 within which fit the rollers 3, 3, and connected together in a rigid manner by radial bridge joints 10 located between the rollers 3, 3. The rollers 3, 3 are held in proper relative position between the ring sections in such a manner that they may be readily removed for renewal, repairs or other purpose,

and as readily replacedin' position, the support- 1 having been previously jacked up away from the rollers to the required extent. In order to accomplish this result, the inner and outer rings 8 and 9 are provided each with open-top seats, within which fit'the end journals 12 of the rollers. The outer ring 9 is provided with a wall 9, closing in the open-top seatsthereof at the outside, and the outer of the roller journals are provided with rounded anti-friction ends 12, which in the outward thrust of the rollers-take a bearing against said wall, said rounded ends also facilitating the removal of the rollers from their seats.

In assembling the parts, the annulus 5 having the rollers 6, 6 is first placed in position upon the support 1, after which the rollers 3, 3 may be conveniently placed in position with the end journals thereof in their open-top seats, or these rollers may be first engaged with their seats and the annulus then placed in'position upon the support. The load 4 is then let down upon the rollers, and the device is complete.

In order that the weight of the load may always be borne upon the rollers 3, 3 and never upon the rollers 6, these rollersp3, 3 have their end journals 12 located slightly above and clearing thebottoms 13 of their seats by intervals 14, said journals turning between and having lateral contact with the side walls 15 of said seats.

The invention is conveniently assembled and as readily dismantled, and is designed.

to efiecta great saving of time and labor. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: I In a device of the class described, a base having a beveled annular track, an outer ring having a series of open-top recess-seats having outer end walls, and a series of openend vertical slots, a support for the load having a diameter less than that of said outer ring to leave said seats and said slots exposed, an inner ring having a series of open-top recess-seats and rigid connection with said outer ring, bearingrollers si1pporting said" rings above said base, pivoted in said vertical slots and removable from the open upper ends thereof, a series of frusto-' conical load-bearing rollers upon said track walls of the seats of the outer ring to take and upon which rests said support, said rollthe thrust and to facilitate the removal. 10 ers havmg end Journals engaging the recess In testimon whereof I,afiix my signature, seats of the mugs and being removable with in presence 0 two witnesses.
